HEEL-PLATE FOR RUBBERS.

SPECIFICATION forming part of Letters Patent No. 366,391, dated July 12,18117.

' Application filed April 2, 1887. Serial No. 233,366. (No model.)

To aZZ whom it may concern.-

Be it known that we, VILLIAM E. FRANK and PETER REIDEL, of Utica, in thecounty of Oneida and State of New York, have invented certainnew anduseful Improvements in Heel- Ilates for Rubbers; and we do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

Our invention relates to an improvement in rubber heel-plates; and itconsists of the mechanism and constructionhereinafter described.

It is a well-known fact that rubbers usually first wear out on the rearof the heel, and our device is intended to obviate this tendency toexcessive wear, and thus increase the durability ofthe rubber. It isalso a well-known faetthat as soon as the corrugat-ions upon the bottomof a rubber become worn smooth they become very slippery and unsafe towear upon icy walks or streets. Our invention aims to yfurnish asubstitute for these corrugations,

with the advantage that the means employed are such that they can beconcealed or shielded within the body of ourinvention when not required,thus offering no obstruction to pedestrianism, and obviating damage tofloors or carpets, in contradistinction to the action of the usualheel-plate or Creepers In the accompanying drawings, Figure 1 representsa side elevation of our improved rubber with part of the heel brokenaway to show the interior mechanism of our device. Fig. 2 represents aportion of an end elevation of the rear or heel of the rubber with ourimproved device attached. Fig. 3 represents a a rubber with our improveddevice attached. The broken lines in Fig. 1 also representasection online A A of Fig. 2.

Like figures refer to like parts in the several figures.

Our device consists, essentially, of a case or shell, 1, Figs. `1, 2,and 8, constructed of any suitable material, and so formed as to conformto the contour of the outside of the rubber heel. On the inside of theheel of the rubber,

and con forming to the general eontoui` thereof,

we provide a plate of metal or other suitable material, as shown insection 2, Fig. 1. This plate conforms in general superficial outline tothat of the outer easeofshell 1. The outer case or shell, 1, and innerplate, 2, are placed, respectively, on the outside and inside of theheel of the rubber, and riveted or screwed together, as shown at 3,Figs. 1, 2, and 3, inclosing or clamping the material of the rubberbetween them, as shown at 3, Fig. 1. Plate 2, Fig. 1, in addition to itsfunction as part of the means employed in holding the outer shell, 1, inplace, also acts as a protection against wear to the interior of therubber heel from the heel of the boot or shoe. In the interior of thecase or shell 1, and resting at its ends upon the interiorsurface ofthebottom thereof, we provide elliptic spring 4, Figs. 1 and 2. Pivoted orotherwise suitably attached to spring 4 we provide pin 5, Figs. 1, 2,and 3. A suitable aperture is provided in the bottom of the case orshell for introduction of pin 5, as shown at 6, Figs. 1,- 2, and3. Inthe eonstruction shown we perforate spring 4 for the introduction of pin5, which we provide with a shoe or curved-shaped head, as shown at 7,Figs. 1 and 2. XVe also provide a projecting ledge'orlug of metal orother suitable material, as shown at S, Figs. 1 and 2. Between ledge orlug 8 and shoe-shaped head 7 we introduce a wedge, as shown at 9, Figs.1 and 2. Projecting from the side of wedge 9, and extending outwardlythrough a suitable slot provided in the case or shell 1, we provide apin, 10, Figs. 1, 2, and 3, or its equivalent, the purpose ofwhich is tomove wedge 9 back and forth between ledge 8 and shoe-shaped head 7./Vhen wedge 9 is in its retracted position, the pin 5 is drawn up intothe body or case or shell 1, so that its point does not projectontwardly therefrom. \Vhen wedge 9 is pushed forward into the positionshown in dotted lines in Fig. 2, its action upon spring 4 compresses itand causes pin 5 to protrude from the ease or shell and actsubstantially as a spur or ereeper.

It is evident that more than one pin or spur can be embodied in theconstruction of our device; hence we do not limit ourselves to the useof one pin. Ve also preferably corrugate IOO or roughen the bottom ofease or shell 1, 'as

shown at11 11 11, Fig. 3. Slight changes in the construction of ourdevice could evidently be made without departure from the spirit of ourinvention. Consequently we do not limit ourselves to the precisestructural details herein described.

What we claim as new, and desire to secure by Letters Patent, is l 1. Arubber boot or shoc,fin combination with an outer case or shellencircling vthe rear lower portion of the heel and conforming to itscontour, its lower portion being on substantially the same plane withthe bottom of the heel, the bottom portion having a 'corrugated surface,,the interior plate conforming substantially to the interior of theheel, and means for holding the outer case or shell and thevinteriorplate in fixed relat-ion to the heel of the boot or shoe, substantiallyas set forth.

2. A rubber boot or shoe, in vcombination with an encircling case orshell fitting the contour of the rear outside portion of the heel, thelower portion of the case or shell being on substantially the samehorizontal plane with the bottom of the heel, the inner plate, and meansfor holding the outer shell and the inner plate in contact with therubber, substantially as set forth. l

3. A rubber boot or shoe, in combination with an encircling case orshell fitting the contourl of the rear portion of theheel, the innercontour of the case or shell beingprovided with a recess, the movablepin operated by l movable wedge and spring, substantially as set forth,whereby the pin is extended or withdrawn fromthe lower surface of the`case or shell, and means for holding said case or shell to theheel ofthe rubber, substantially as sct forth.

4t. A rubber boot or shoe, in combination with an interior and anexterior encircling case or` shell fitting substantially the contour ofthe rear portion of the heel, the interior of the outer case or shellbeing provided with a recess, the movable pin operated by the m0vablelwedge over the pin for projecting ithe pin below the lower surface ofthe outer case, a spring forfengaging and moving the pin up ward, andmeans for rigidly holding the twocases in contact with the rear of therubber, substantially as set forth.

5. In a heel-plate for a rubber boot or shoe, the combination of anencircling case conforming-to the contourof the rear of the heel, u
